ASSIGNORS T0 THE MAYTAG COMPANY, OF NEWTON, IOWA, A CORPORATION Ol' DELAWARE WRINGER I Application leq June 8,

The present invention relates to wringers, such asJ are used in connection with power washing machines.

Among the objects of the invention 1s to a novel wringer frame provided with guiding webs for Yguiding articles or clothes between the rolls. in the frame and 'to guide them away as they pass through" the rolls.

.Another object of the invention is to provide a novel wringer frame having a longitudinal opening therein below the rolls for directing water dripping from the rolls to means associated with the. opening which divert the water to either side of the wringer.

A further object of the invention is toprovide a novelV means for diverting water which drips from the rolls during the wringingoperatioii back into the tub or other container to which the wringer may be attached. rEhe invention comprehends the idea of mountingl this diverting means or drain plate in the frame of the wriiigcr so that clothes passing through the Irolls thereof will .not tip or tilt the plate to divert the water from `the rolls to the wrong side of the wringer and away from the tub or kother container.

Another object of the invention is to provide means for automatic tilting or tipping the drain plate or diverting means to direct the water from Athe rolls back into the tub or other container to which the wringer may be attached. y e

As a further object of the' invention, means are' provided for preventing vibration of the drain` plate when the wiinger is operating.

In a specific embodiment illustrative 'of the invention, the lower pait of the frame is provided with web or skirt portions on both sides of-thefiame, sloping downwardly and away from the lower wr-inger rolls, and web or skirt portionssloping downwardly and towardthe lower wringer roll .and terminating i'n spaced relation to each at approximately the longi-' 1929. Serial No. 369,294.

"or web portions serve as guides forv the clothes or objects passing through and out between the rolls. They are spaced from the lower rolls sufi'iciently far to be ofuse as guides and also prevent the clothes as they pass through the rolls from becoming en# 4tangled with the rolls or other mechanisms associated with the wringer. rllhese' skirt or web portions also form a hopper with 'a longitudinal opening which directs water dri ping from the rolls to means below. 'le skirt or web portions" are of further importance inasmuch as they provide ahousing 'for a drain plate pivotally mounted in the ends of the frame and which is directly loelow the longitudinal opening in thehopper. This housing completely encloses the drain plate, which is automatically tipped or tilted to either side of the wringer dependent upon the direction of rotation of the rolls,

and prevents the clothes passing through the wringer from becoming lodged thereon and .tipping or tilting it in a wrong direction.

rl`he drain plate or diverting means is provided with an upstanding arm which passes through the longitudinal opening, the end of which engages an arm of a dog or cam frictionally mounted on None end of the lower roll. The arm of the dog or cam on the lower roll shaftbears against the arm of the \tiltabl'e drain plate or diverting means to tip yor tilt the drain plate in either' of two directions depending upon the direction of rotation of the roll.

A further object of the invention is to provide a novel wringer frame in which thev lower roll is removably mounted. In the specilic embodiment selected to illustrate the invention, one end of the frame is provided with an aperture through which a coupling socket from a gear head projects into the frame. The other end of the frame is vided with a cradle-shaped portion.

lower roll is provided with a shaft, one endv of which is adapted to be inserted into the coupling socket and the other end is provided with a bearing adapted to resti-on the cradle-shaped portion. The coupling socket position.

ling the ends of the shaft of the upper roll.

The upper roll is frictionally driven bythe lower roll and may be swung out of its normal operative position for cleaning or for repairingthe wringer mechanism. In its normal operative position, l.means are pro vided for holding the upper roll in such position.

The invention also comprehends other objects, advantages, capabilities and features which will later appear, and are inherently possessed thereby. i

Referring to the drawings:

Fig. 1 is a view in side elevation' of an embodiment selected to disclose the invention, with parts Abroken, away to show the construction'of the lower portion of the frame and drain plate.

Fig. 2 is a bottom plan view of the emto register with holes as at 7 in the frame 1, and the casing is connected to the frame and held in position by bolts 82 Enclosed within the casing and meshing with the gearing in the gear casing 4 is a projecting socket coupling 9 adapted to project through an aperture 10 in the end of the frame and into the space between the standards 2 of the frame 1. A wringer roll 11 having a resilient rubber surface is provided and is mounted on a shaft 12 having an extending portion 13, the end of which is hexagonal shape to form a torque 14 which fits into and couples with the 'socket coupling 9 and is driven thereby. Mounted upon the other end'of the shaft 12 is a bearing casing 15 in which are secured bearings (not shown) surrounding t-he end of the shaft. The bearing casing 15 isv adapted to seat and rest upon the lower portion 16 of a cradle-shaped depression 17 formed between the standards or upright end members 3 at the one end of the frame 1. This roll 11 may be removed from the frame 1 by lifting the end resting in the cradle-shaped depression upwardly and removing-the' extended portion of the shaft n with the torque 14 from the socket coupling 9. .y l

At the lower portion of the frame 1 1s `provided skirts or webs 18 and 19 extending longitudinally on both sides of the frame 1, and intersecting the standards 2 and 3 to bodiment selected to illustrate the invention ,/form a ueted guide Surface as at 20 at both showingin detail the drain plate and means for preventing vibrationof the same during operation of the wringer.

Fig. 3 is a top plan view of the embodi-4 ment shown in Fig. 1 and 'showing the to section of the frame released and turne over to expose the parts beneath.

.-Fig. 4.is a vertical cross sectional view taken in the plane represented by line 4 4 of Fig. 1 and showing in dotted lines the top section of the. frame in its turned-back Fig. 5 is a vertical cross sectional view taken in the plane represented by line 5 5 of Fig. 1, showing theconstruction of the drain plate and its relation to the opening beneath the lower roll.

Fig. 6 is a top plan view of the end of the frame to which the gear head is connected with the lower roll, the top section of the frame being removed toshow the. position of the drain plate arm extending up through the opening in the lower part of the frame.

Referring now more in detail to the drawings, the embodiment selected to illustrate the invention, comprises a wringer frame 1..

f. provided with standards or hollow upright end members 2 at one end and 3v at the other end. A gear-head casing 4 enclosing suitable gearing anddriven from a source of power (not disclosed) is provided with flanges 5 haring bolt holes as at 6 which are adapted ends ofthe frame. The webs 19 are spaced from the roll 1,1, the intersection of which with the skirts or webs 18 form the guide ridges 21 at Iapproximately the height of the longitudinal center line or axis of the roll 11. The webs or skirts 18' between the standards extend vdownwardly and away from the ridges 21 to form guiding surfaces. for

clothes or other articles passing into and through the wringer, while the webs or skirts 19 extend downwardly and inwardly from the ridges 21, the termination of the edges of which form an opening 22 extending longitudinally beneath the roll 11 from the 11p portion 22 which extends downwardly from the crade-shaped portion 17 between the standards 3 at one end of the frame, to a somewhat similar lip portion 22" extending downwardly `from a recess portion 23 at the other end of the frame 1 and between the' standards 2.

The downwardly and outwardly sloping webs 18 are so positioned relative to the wringer rolls that they serve as hand rests for the operator as clothes or the like are being fed into andl through the rolls as Well 'as to serve as hand guards to prevent the A spring 28 encircling the trunnion 26 and having one end bearing against a wall 29 of the drain plate and the other end bearing against a pin 30 projecting through the slidable trunnion 26, provides means for holding the slidable trunnion 26 lin its normal extended position and to exert pressure upon the drain plate 24 and to hold the 'same {irmly in adjusted position to prevent vibration during the operation of the wringer, and also to permit the drain plate to be easily removed from its bearing in the frame 1 for repairingthe same or other -mechanisms of the wringer. y

A split cam or dog 31 is mounted upon the extended portion 13 of the shaft 12, being held in frictional engagement with the seating in an annushaft 12 by a ring o... lar groove 33 around 'the split cam or dog. One of the split members of the cam or dog 31 is provided with an extending arm 34 which engages or bears against the arm 27 of the drain plate 24 when thesame is in itsv normal adjusted operative positions. The cam or dog 31 normallyxbears against the arm 27 to keep the drain plate 24 vin a tilted position so that the water dripping from the wringing operation` through the opening 22 is diverted or directed back into the tub or other container to which the wringer may be connected. If the lower roll is rotated iii a reverse direction, the cam or dog 31 will be Vswung around vbecause of its rictional mounting on the shaft 12 to bear or engage the arm 27 on the other side lto tilt the drain plate 24 in a reverse direction and thereby direct the water to the other side of the wringer.

Pivoted to the standards or upright end members 2 and 3 of the frame is a pair of cross members or ears 35 and 36 to which is pivoted a cap platev 37, having a pivotal member or members 38 iattened as shown in Fig. 3 and as indicatedvby the line 39 in Fig. 4. It will be seen that when the cap plate 37 is in the position shown in Fig. 4, the member'or members 38 will engage hooks or latch members 40 passing up through the standards or upright end members opposite- G ly located to those standards or upright members to which the cross members or ears 35 and 36 are pivotally connected. The hooks or latchimembers 40 extend down through I i the top if the standard and into the hollow compartment below, and are provided with a nut 41 engaging the threaded end of the hook and between which and the top plate ofthe standard is a spring 42 for holding the hook or latch member 40 in engagement with the member 38 of the cap plate 37. The cross members 35 and 36 are provided with extending portions 43 which provide a seating means for bearing casings 46 adapted to hold bearings and in which are journaled the ends of a shaft 44 upon 'which is mounted the roll 45.

When the cap plate 37 is in the position as shown in Fig. 5, the member or members 38r will engage the hook or latch member 40 to hold the cross members or ears- 354 and 36 down in the position intended for wringing and the upper roll 45 will frictionally contact with the lower roll 11 and be driven thereby, but that when the cap plate 37 is turned or opened to the position shown in Fig. 3 or by dotted lines as in Fig. 4, the pivots v38 will be released from the hooks or latch members so that the cap plate, cross members 'and upper wringer roll may be turned on the pivots connecting the cross members or ears with the standards or upright members of the frame.

This structure makes it very easy to release the tension pn the rolls, inthe event that the hand should get caught between the rolls, or. clothes` get hunched in going through* the wringer. 1t also makes it easy to open up the wringer for the purpose of taking out the wringer rolls. r1`he bearing casings 46, in which are positioned bearings about the j ournaled end of the shaft 44, are removably mounted upon the shaft but are retained on the shaft when the roll 45 is removed from the extending portions 43. Whenever it becomes necessary to remove the upper roll because of injury or'because of the wear, a new wrlnger roll with its bearlng caslngs posltioned on the ends thereof, may be easily.

mounted in the extending portion 43 of the ears or cross members. l
